目前,Su1zer公司又将一种新型的四冲程中速柴油机投入了市场。它可以满足船用主机和船用辅机90年代的要求。命名为S20的柴油机系列,缸径为200mm,行程为300mm。发动机系列有6、8、9缸机,转速范围720～1000r/min,功率范围570～1305kW。柴油机的设计,考虑了持续运行时燃用重油和船用柴油。通过应用ZA和AT系列四冲程柴油机上经过考验的技术,S20系列柴油机具有很低的燃油消耗率、燃烧完全、高功能燃料喷射系统和匹配良好的增压系统。它具有高的可靠性和长的使用寿命。其检修周期在燃用重油时至少为2年,在燃用柴油时可达4年。
At present, Su1zer company put a new type of four-stroke medium-speed diesel engine into the market. It can meet the marine mainframe and marine auxiliary 90’s requirements. Named S20 of the diesel engine series, bore 200mm, travel 300mm. Engine series 6,8,9 cylinder machine, speed range 720 ~ 1000r / min, power range 570 ~ 1305kW. Diesel engine design, considering the continuous operation of burning heavy oil and marine diesel. By applying proven technologies on the ZA and AT series four-stroke diesel engines, the S20 Series diesel engines offer low fuel consumption, complete combustion, a high-performance fuel injection system and a well-matched boost system. It has high reliability and long service life. The overhaul period is at least 2 years when burning heavy fuel and 4 years when burning diesel.
